Peripheral neuropathy is an uncommon manifestation of systemic lupus erythematosus and has not yet been characterized in pediatric patients. We report the clinical and electrophysiologic features of peripheral neuropathy in one child and three adolescents with lupus erythematosus. There were three females and one male. The peripheral neuropathy followed the onset of lupus erythematosus by a mean of 3 years. The onset of the neuropathy correlated with lupus erythematosus activity and presented with either severe pain or dropfoot. Nerve conduction studies revealed sensory and motor polyneuropathy in all patients and mononeuritis multiplex in two patients. Only one patient had associated central nervous system involvement at that time. All patients were positive for IgM and IgG anticardiolipin antibodies. Patients were treated with steroids, gabapentin, carbamazepine, azathioprine, and cyclophosphamide. Response to treatment was variable: two patients recovered and two had a partial response. Although an unusual manifestation, peripheral neuropathy should be kept in mind as part of the neurologic spectrum in lupus erythematosus. It is not necessarily associated with central nervous system disease. A role for antiphospholipid antibodies in the pathogenesis is suggested.
